KOYO bearings are usually moved with the outer ring of axial position to the axial internal clearance. Main common methods of the axial internal clearance of the bearing has two, that is, adjust the shim method and adjusting bolt method.
1. adjust the shim method:
In KOYO bearing end cover and bearing block end surface Zhijian filled placed a group soft material (soft steel tablets or elastic paper) gasket; adjustment Shi, first does not placed gasket loaded Shang bearing end cover, side uniform to screwed tight bearing end cover Shang of screws, side with hand turn axis, until bearing scroll body and outer ring contact and axis internal no gap weizhi; then measurement bearing end cover and bearing block end surface Zhijian of gap, again plus bearing in normal work Shi by needs of axis to gap; this is by needed filled placed gasket of total thickness, Then insert the prepared gasket placed on the bearing end cover and housing between the end and finally tighten the screws.
2. adjusting bolt method:
KOYO bearing rings on the pressure ring pressure, adjust bolt compression; before the compression adjustment, first measure the pitch adjustment bolt, then tighten adjusting bolt slowly until the bearing until there was no gap, and then figure out the rotation angle adjustment bolt. For example pitch of 1.5mm, bearing the clearance needed for the proper functioning, then the required rotation angle adjustment bolt to 3600x0.15/l.5=360 when reverse 360 adjustment bolt, the micro-bearings axial clearance access to 0.5mm, and then use the gaskets fixed to stop.
